Opening statements are expected today in the federal trial of West New York Mayor Felix Roque and his son, who are charged with hacking into and bringing down a political opponent’s website.

There were eight women and four men seated in the jury box when yesterday’s proceedings ended at 4:30 p.m., but the defense can still dismiss up to six jurors and the prosecution also has up to four peremptory challenges remaining.

A panel of about 60 potential jurors entered District Court Judge Kevin McNulty’s courtroom at 10:50 a.m. Roque wore a black suit and his son Joseph a grey pinstripe suit and they appeared relaxed as they sat at the defense table with their attorneys. The mayor said he had no comment on the trial.

Among the questions the judge asked jurors were whether the jurors had any association with the defendants, West New York, or potential witnesses.

The Roques are accused of attacking the website www.recallroque.com, which was anonymously set up last year by Hudson County Freeholder Jose Munoz, a Roque foe who it was learned last week has been an FBI informant since 2011.

Both Roques are charged with unauthorized access to computers and using that access to harass individuals they saw as enemies. They are also charged with a count of conspiracy that also refers to the alleged harassment. Each count carries a possible prison sentence of up to five years upon conviction.

According to prosecutors, on Feb. 8, 2012, Joseph Roque hacked into online accounts connected to the website and used that access to sabotage it. Then, it is alleged, Mayor Roque harassed and attempted to intimidate several people associated with the website.

The defendants filed motions for dismissal of the charges on six separate grounds, but each was denied by McNulty.

Assistant U.S. Attorneys Barbara Llanes and Jud Welle are handling the case. The mayor’s lawyer is John P. McDonald of Somerville and his son’s lawyer is John Azzarello of Chatham.
